MEDIUM: mux-h1: use task_kill() during h1_takeover() instead of task_wakeup() task_wakeup() passes the task through the global run queue under the global RQ lock, which is expensive when dealing with large amounts of h1_takeover() calls. Let's use the new task_kill() instead to kill the task. By doing so, a scenario involving approximately 130k takeover/s running on 16 threads gained almost 3% performance from 319k req/s to 328k.
